The fabled Packard factory in Detroit — it could be yours for $21,500

It’s the factory on East Grand Boulevard in Detroit, where some of the most famous luxury cars of the 1930s and 1940s were built. You see them at the big-deal concours d’elegance all over the world, such as Pebble Beach and Amelia Island.

Packard was also known for the big engines it made for American fighting machines during World War II — it built V12 engines, with up to 1,500 horsepower, for the Navy’s PT (Patrol Torpedo) boats.
